A bstract : In the data set collected by the authors in freshly excised breast tissue, the admittance loci generally differed from circular arcs, rendering the calculation of the usual set of parameters impossible. Alternative parameters were used for the analysis of these data. The present study consists of the definition and evaluation of a set of such parameters aimed at the characterization and differentiation of breast tissues. These parameters were defined so that their calculation does not require the fit of circular arcs to the experimental points and is independent of any equivalent circuit model. The results of the statistical analysis showed significant differences between most of the tissue groups, especially between cancerous tissue and all the other groups, which confirmed that impedance spectroscopy can be considered as potentially suitable for breast cancer detection.
